DLPI_BIND(3DLPI) Data Link Provider Interface Library Functions DLPI_BIND(3DLPI)

dlpi_bind - bind DLPI handle

cc [ flag ... ] file ... -ldlpi [ library ... ]
#include <libdlpi.h>
int dlpi_bind(dlpi_handle_t dh, uint_t sap, uint_t *boundsap);

The dlpi_bind() function attempts to bind the DLPI handle dh to the SAP sap. The handle must be in the DL_UNBOUND DLPI state and will transition to the DL_IDLE DLPI state upon success. Some DLPI MAC types can bind to a different SAP than the SAP requested, in which case boundsap returns the actual bound SAP. If boundsap is set to NULL, dlpi_bind() fails if the bound SAP does not match the requested SAP. If the caller does not care which SAP is chosen, DLPI_ANY_SAP can be specified for sap. This is primarily useful in conjunction with dlpi_promiscon() and DL_PROMISC_SAP to receive traffic from all SAPs. If DLPI_ANY_SAP is specified, any transmitted messages must explicitly specify a SAP using dlpi_send(3DLPI).

Upon success, the caller can use dlpi_recv(3DLPI) to receive data matching the bound SAP that is sent to the DLPI link associated with dh. In addition, the caller can use dlpi_send(3DLPI) to send data over the bound SAP address associated with DLPI handle dh. The physical address of the bound handle can be retrieved with dlpi_info(3DLPI).

Upon success, DLPI_SUCCESS is returned. If DL_SYSERR is returned, errno contains the specific UNIX system error value. Otherwise, a DLPI error value defined in <sys/dlpi.h> or an error value listed in the following section is returned.
